[Omake] file predicate documentation error?

[Prashanth Mundkur]

According to the documentation for test():

-s file : The file is empty

But the behaviour is exactly the opposite: -s returns false for empty
files, and true for non-empty files.  This is consistent with the
source, which uses is_nonempty_file to implement -s.

This seems like a documentation error.
